Abstract

The general patterns of the soil macrofaunal communities in the most common land use types (i.e., primary forests, rice crops, pastures and fallows) of the Brazilian Amazon are summarized. Modifications in the abundance and species diversity of communities according to land use changes and scales are particularly addressed. Also presented are case studies conducted in Benfica and Maraba (Para), Manaus (Amazonas) and Acre-Rondonia, illustrating the large and interregional variations of geological substrate, climate and land use impacts on macroinvertebrate communities.
